Thank you for viewing! I've made a winter-spec T-shirt that can be worn instead of a vest, even in winter!! This is a "defective item." The reason it's considered defective is because the stitching is somewhat uneven. Size: Large S size Width (flat measurement): approx. 58cm Length: approx. 63cm (back) ⭐︎ I personally dislike the bulkiness and thickness that comes from rolling up the sleeves of sweatshirts, etc., so I've been looking for a winter-spec T-shirt to wear over an undershirt every year... But it seems there's no demand for winter-spec T-shirts, as I can never find one every year (´༎ຶོρ༎ຶོ`) There are ponchos, though... Having sleeves makes it more reliable than a vest!! ~Although it's handmade, for those who like a handmade feel, those who like one-of-a-kind items, and those who can relate, how about it?~ Material ❶ Sweatshirt fabric with a loop back that looks like it's knitted with yarn. I think it's a wool blend, but I've forgotten the ratio. Color: Heathered natural It's a thick, fluffy, premium knit fabric from Fujii Textile Co., Ltd. in Kyoto. It's warm, and of course, it stretches greatly horizontally, so it's incredibly comfortable! ◉ Material ❷ Quilted knit (unknown ratio) Color: Blue-toned dots The ratio is unknown, but it seems to be a blend of cotton and synthetic fibers. The quilted batting in between is a synthetic fiber batting like willy yarn, so it should have good heat retention ◉ [Other] Aran-style ribbed knit If anyone is interested, please consider it. If you have any questions, feel free to comment!
